220 or 195.
Those options are the most likely.
Answer:
Step-by-step explanation:
You can use the FOIL (first, outer, inner, last) to find the answer.
(7x - 4) · (8x + 5) = (7x · 8x) + (7x · 5) + (-4 · 8x) + (-4 * 5)
=
=
Let s be the length of a section for plants.
Because opposite sides in a rectangle are equal we can state that 7 + 5s = 4 + 6s
Subtract 5s and 4 from both sides to get 7 - 4 = 6s - 5s which simplifies to 3 = s
The length of the wall = 7 + 5 x 3 = 22 ft
Check on opposite side: 4 + 6 x 3 = 22 ft
Answer:
125.72
Step-by-step explanation:
radius equals pi(r)2
rectangle equals b times h
radius is 6.28
rectangle is 132
you now subtract them
132 minus 6.28 which is 125.72
hope this helps
Answer:
The number of ways those textbooks could be distributed among the students is expressed by a combinations of 8(books) to 5(students), which is
Step-by-step explanation:
The order in which the students get the textbooks is not important. For example, A,B,C,D and E getting the textbooks is the same outcome as B,A,C,D and E. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
In this problem
5 textbooks to 8 students. So
The number of ways those textbooks could be distributed among the students is expressed by a combinations of 8(books) to 5(students), which is
